超细颗粒增强铝复合材料钻削特性研究

摘要

The experimental conclusions of drilling super-fine particle rein f orced Al matrix composites was presented, induces regularity of drilling force w hich is influe nced by many factors, such as drill parameters. The ratio of longitudinal force to drilling torque is adopted to describe drill property of this material. As fo r as drilling force is considered, high speed steel bit is enough to drill these material.%通过超细颗粒增强铝复合材料钻孔试验，找出了钻削用量等因素对 钻削力的影 响规律，并用轴向力与扭矩之比值来表示铝复合材料的钻削特性；从钻削力考虑，高速钢钻 头完全能满足超细颗粒（＜0.5μm）增强铝复合材料的钻孔要求。
